I've been reading Tapas webcomics for a while, but I wasn't immersed in the community because I lacked an account.
Anyway, the book wasn't doing so well on Amazon (no advertising budget) and I needed to give it another round of editing, so I thought about relaunching it as a webserial. It actually started as a webserial, but Reddit at the time was not the place for that.
Of the serial novel platforms that pay, Tapas seems to have the best business model and market share. The other platforms charge too much, aren't as well-known, or both.
